Win7 PC shutting down

Diddy89 · Nov 1, 2013

I’ve used my HP Pavilion for 4 years now without any issues. Recently it started shutting down randomly. No blue screen, no warning, just dies. Checking the Event Viewer didn’t show anything prior to the shutdown. Replaced the power supply and it continues to randomly shutdown.
Ran diagnostics on all the hardware; motherboard, memory, processor. All tested good. While the PC was up, I would run SPECCY and the temps were all within tolerance. Ran system recovery to previous point in time and tried using the Win7 installation disks to repair the OS, but couldn’t find any problems with the OS.
Bought a new hard drive and tried to install Win7 on the new hard drive, but the PC would shutdown every time right after Windows 7 files were extracted. Put the same hard drive in my Dell PC and was able to perform a complete install of Win 7 on the HD.
I can boot to Safe Mode and the PC will stay up for days, but as soon as I boot to Win7 normally, it will shut down after a period of time.
So after all this, it has to be a driver issue, right? If so, how can I determine the specific issue. Or is there something I may have missed?

the only choice i see tbh is format. otherwise its really hard to locate which driver is cousing this problem, you can just download all drivers and uninstall and reinstall.

How the hell do people draw the conclusion of 'driver issue' from what is so obviously a hardware fault?
- It's 4 years old.
- Drivers do not cause system shutdowns, it might reboot and 'pass over' a BSOD, but it will NEVER shutdown due to a driver issue. (Unless the driver just hides another common problem with common or cheap hardware, which some video drivers do).

Touché. I’m just confused as to why I can keep the PC powered up for days in Safe Mode, but it crashes on a normal boot. I’ve run several different hardware diag programs and can’t find anything at fault.

Because it uses less power in Safe Mode and certain hardware never enters their accelerated I/O modes?
- Which points at power, or a defective power related circuitry.

I think your motherboard has finally had it dude.

I mentioned this in another thread, but try enabling PCI Lock via MSCONFIG whilst in Safe Mode, then booting or cold booting back into Normal Mode.
